Description
Technical Field
The invention relates to the technical field of adhesives, and particularly relates to a glass adhesive and a preparation method thereof.
Background
Glasses are generally classified into oxide glasses and non-oxide glasses by main component. The non-oxide glasses are few in variety and number, and mainly include chalcogenide glasses and halide glasses. The anions of the chalcogenide glass are sulfur, selenium, tellurium and the like, can cut off short-wavelength light and pass through yellow and red light, near and far infrared light, and has low resistance, switching and memory characteristics. The halide glass has low refractive index and low dispersion, and is used as optical glass. The organic glass is a polymer obtained by polymerizing acrylic acid and esters thereof, has excellent light transmittance, high mechanical strength, corrosion resistance and easy processing, but is brittle, easy to dissolve in organic solvents, insufficient in surface hardness, easy to brush and the like. Organic glass, because of its brittle texture, requires the use of adhesives when combined with other products.
At present, common adhesives mainly include acrylate adhesives, epoxy acrylate adhesives and ultraviolet curing adhesives. The ultraviolet curing adhesive is composed of a photosensitizer, resin and a monomer as main components, wherein the photosensitizer absorbs light energy to activate and decompose high-activity species, and polymerization reaction of polymerization functional groups of the resin and the monomer is initiated, so that the adhesive is cured and generates strong adhesive force. Compared with other two adhesives, the ultraviolet curing adhesive has the advantages of no need of heating equipment, high curing speed, environmental friendliness, automation in production, low cost, simplicity in preparation and long-term use, and therefore plays a key role in research and development and quality improvement of glass products.
According to the difference of polymerization reaction types, the ultraviolet curing adhesive is divided into a free radical type and a cationic type, wherein the monomer and the resin of the ultraviolet curing adhesive contain acrylate groups, and the monomer and the resin of the ultraviolet curing adhesive are mainly epoxy groups. Among them, the radical polymerization has the advantages of fast reaction speed, easy preparation, strong adhesion, durability, good weather resistance, etc., so it is widely used. However, the volume shrinkage is large, air has a serious polymerization inhibition effect, and the water resistance and the re-peeling property are poor, so that the further development of the composite material is limited; the cationic ultraviolet curing agent has small polymer shrinkage and no influence on air due to the existence of an epoxy group, but has slow polymerization speed, is sensitive to water vapor, can corrode some bonding materials due to acid decomposed by a cationic initiator, and has low impact strength and peel strength, so that the application of the cationic ultraviolet curing agent is greatly limited.
Therefore, it is highly desirable to provide a glass adhesive with high reactivity, fast curing speed, impact resistance, peeling resistance and excellent bonding property and a preparation method thereof, so as to meet the market demand.
Disclosure of Invention
The invention aims to solve the problems in the prior art and provide a glass adhesive with high reactivity, high curing speed, impact resistance, peeling resistance and excellent bonding comprehensive performance and a preparation method thereof, by adopting five components of polyurethane resin, acrylate monomer, N-dimethylacrylamide, organosilicon with reactivity activity and ultraviolet initiator, organosilicon is added in the polymerization reaction for synthesizing acrylic resin, so that the organosilicon is directly grafted on the molecular chains of acrylic ester, polyurethane resin and N, N-dimethylacrylamide in the polymerization reaction process, thereby obtaining organosilane modified acrylic resin and polyurethane resin with a cross-linked network structure, the adhesive has the advantages that the adhesive performance, the adhesive speed, the high temperature resistance, the weather resistance, the corrosion resistance (20% of acid and alkali) and the yellowing resistance of the adhesive are greatly improved; meanwhile, the N, N-dimethylacrylamide and the acrylic monomer are copolymerized to generate a polymer with high polymerization degree, so that the adhesion, hygroscopicity, antistatic property, dispersibility and compatibility of the adhesive are further improved in a synergistic manner.
In order to achieve the purpose, the invention adopts the technical scheme that:

As a further limitation of the above, the silicone is one or a combination of two of γ -mercaptopropyltrimethoxysilane and methyltriethoxysilane.
As a further limitation of the above scheme, the photoinitiator is any one or more of α -hydroxycyclohexyl benzophenone, 2, 4, 6-trimethylbenzoyldiphenylphosphine oxide, ethyl 2, 4, 6-trimethylbenzoylphenylphosphonate, 2-hydroxy-2-methyl-1-phenyl-1-propanone, benzoin bis methyl ether.
The invention also provides a preparation method of the glass adhesive, which comprises the following steps:
s1, under the protection of nitrogen, adding a proper amount of N, N-dimethylacrylamide into the polyurethane resin according to the weight percentage, and heating and stirring until the polyurethane resin is completely dissolved for later use;
s2, dissolving the acrylate monomer and the photoinitiator in percentage by weight by using N, N-dimethylacrylamide, simultaneously adding organic silicon, heating and stirring until the acrylate monomer and the photoinitiator are completely dissolved, and then dropwise adding the acrylate monomer and the photoinitiator into the polyurethane resin solution prepared in the step S1, wherein the dropwise adding is controlled within 2 hours;
and S3, after the dropwise addition is finished, continuously stirring and reacting for 3-4 hours at the temperature of 80-90 ℃.
As a further limitation of the above aspect, in step S1, the heating temperature is 65-80 ℃.
